The Antonov An-180 was a Ukrainian design for a twin-aisle medium-range propfan airliner. Although the design was completed by the Antonov Design Bureau in 1994, the type was not built. [1]
The An-180 was designed as a replacement for the aging Tupolev Tu-134 and Yakovlev Yak-42 airliners. [2] Antonov was discussing this aircraft in Soviet aviation publications as early as October 1990, describing the An-180 as a 164-180 passenger plane with a range of 1,300 to 1,600 nautical miles (2,500 to 3,000 kilometres; 1,600 to 1,900 miles) and a per-passenger fuel consumption of 14 to 15 grams per kilometre (0.79 to 0.85 ounces per mile). [3] The proposed aircraft was introduced to the world at the 1991 Paris Air Show. [4] As of September 1991, the An-180 had a T-tail design with the propfan engines attached to the aft fuselage, [5] but Antonov later modified the design so that the engines were attached to the ends of the horizontal stabilizer in a conventional tail configuration. [6] In 1992, Ukraine and China were studying whether to jointly develop the aircraft. [7]
In April 1994, a prototype of the aircraft was tested at the Russian Central Aviation Institute's transonic wind tunnel, with follow-up tests in July to finalize the design, but financial problems delayed the completion of the study as of November 1994. [8] By February 1995, joint manufacturing was expected to begin at the aircraft factories in Kharkiv, Ukraine and the Production Corporation Polyot plant in Omsk, Russia. [9] Because of extreme funding shortfalls from the Ukraine government, however, the development of the An-180 was fully suspended by August 1995. [10] In 1999, D-27 engines created by the Progress Design Bureau were still expected to be built for the An-180, according to the CEO of Motor Sich, [11] the Ukrainian manufacturer of the D-27. [12] Subsequent attempts to obtain commercial investment failed, though, and by 2004, the An-180 was no longer an Antonov project. [13]
As of 2003, the fuselage of an uncompleted An-180 aircraft remained in storage in a building used for assembly of Antonov's experimental models. [14]
The An-180 was a conventionally designed low-wing cantilever monoplane with a conventional tail unit. The unusual feature was the mounting of an Ivchenko Progress D-27 propfan mounted at the end of each tailplane. [1] Each propfan was to have a coaxial contra-rotating tractor propeller, and the An-180 was also designed with a retractable landing gear with twin nosewheels, and tandem pairs of mainwheels. [1]
It was planned to have a number of variants with seating starting at 150–156 passengers, to a larger variant for 200 passengers, and it was also planned to build a combination passenger/freight and an all-freight variant. [1] The cabin is configured to use two aisles, with a seating row containing two seats each between an aisle and the adjacent windows/cabin walls, and two seats between the two aisles. [15] The undercarriage can store seven LD3-46 unit load devices. [1]
